The effects of titanium dioxide nanoparticles on cadmium bioaccumulation in ramie and its application in remediation of cadmium-contaminated soil

Alexandria Engineering Journal, Journal Year: 2023, Volume and Issue: 86, P. 663 - 668

Published: Dec. 15, 2023

Cadmium (Cd) is a toxic heavy metal contaminant in agricultural soils. Phytoremediation using hyperaccumulator plants promising remediation strategy. This study investigated the effects of TiO2 NPs on Cd uptake and accumulation ramie (Boehmeria nivea L.) grown Cd-spiked soil. The aim was to evaluate potential application enhance phytoextraction efficiency for removing from contaminated Ramie cultivated soil spiked with 5 mg/kg Cd, or without 500 NPs. results showed significantly increased concentrations roots, stems, leaves by 35%, 75%, 278% respectively, compared control plants. levels reached 146 roots 102 bioconcentration factor rose 21.6 29.2 translocation 0.3 0.7 nanoparticles. indicates bioavailability shoots. higher accumulation, especially leaves, demonstrates improve ramie's capacity. With NP treatment, decreased an estimated 20–30% after 8 weeks cultivation, indicating enhanced phytoextraction. provides evidence that can phytoremediation like Cd-contaminated

Study on tetracycline degradation in wastewater based on zero-valent nano iron assisted micro-nano bubbles

Alexandria Engineering Journal, Journal Year: 2023, Volume and Issue: 86, P. 577 - 583

Published: Dec. 14, 2023

The presence of antibiotics in wastewater has become a significant concern due to their potential environmental impact and contribution antibiotic resistance. In this study, we investigated the degradation tetracycline, commonly used antibiotic, using system based on zero-valent nano iron assisted micro-nano bubbles (MB/nZVI). synthesized nZVI-BC composite, consisting particles loaded onto phosphoric acid-activated biochar, served as an efficient adsorbent for tetracycline removal. Our findings revealed that combination MBs nZVI significantly enhanced efficiency tetracycline. MB/nZVI exhibited highest removal rate 82.81% after 2 h reaction, surpassing performance MB alone, conventional bubble (CB)/nZVI-BC systems. Furthermore, showed superior at dosage 25 g/L flow 30 mL/min. pH condition had no effect system. results demonstrate use be sustainable approach remediation tetracycline-contaminated wastewater.

Abstract Advanced electronics and telecommunication devices rely on electromagnetic (EM) waves of a wide frequency range during their operation, thereby necessitating the development efficient ultrathin materials for interference (EMI) shielding across multispectral EM waves, particularly those exceeding 100 GHz, equivalent to millimeter wavelengths. Here, this study reveals that highly crystalline Ti 3 C 2 T x MXene exhibits excellent EMI performance from kHz 110 along with outstanding environmental stability processability solution coating film fabrication. Notably, films exhibit highest electrical conductivity (18,000 S cm −1 ) remarkable (maintaining >95% over one year), coupled effective (up 106 dB at GHz an thickness 10 µm), surpassing five other MXenes, including Nb CT , V conv.‐Ti CNT Mo different synthetic materials. Furthermore, increasing thickness, conductivity, enhances performance. These results demonstrate potential applying MXenes next‐generation portable electronics, radar systems, autonomous vehicles. This also provides insight into fundamental mechanisms related material waves.
